A control system for an elevator is separated into a first assembly allocated outside and a second assembly allocated inside an elevator shaft. The first assembly includes a power switch for turning on/off the control system, a light switch for switching a light inside the shaft, a safety unit for protecting electrical safety of the control system, a communication unit for data communication with the elevator and/or an external communication device, and a bypass device for bypassing a safety chain of the elevator. The second assembly includes a power supply system for driving the elevator and/or for the safety chain, a monitoring system for monitoring the safety chain, a drive control unit for a drive motor, and a processor for data processing of the control system. The first assembly and the second assembly can communicate with each other and be connected respectively as segments into the safety chain.
